E09.331Drug or chemical induced diabetes mellitus with moderate nonproliferative diabetic retinopathy with macular edema

E09.331 is the ICD-10-CM diagnosis code for drug or chemical induced diabetes mellitus with moderate nonproliferative diabetic retinopathy with macular edema. It belongs to category E09 (drug or chemical induced diabetes mellitus), block E08-E13 (diabetes mellitus) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within E09.33 (drug or chemical induced diabetes mellitus with moderate nonproliferative diabetic retinopathy), E09.331 is specifically for drug or chemical induced diabetes mellitus with moderate nonproliferative diabetic retinopathy with macular edema. Related codes cover without macular edema (E09.339).

Codes in this range require a 7th character: 1 for right eye, 2 for left eye, 3 for bilateral and 9 for unspecified eye. Use placeholder "X" characters to fill any empty positions before the 7th character.

Code first: poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4).

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5). Use an additional code to identify control using: injectable non-insulin antidiabetic drugs (Z79.85), insulin (Z79.4), oral antidiabetic drugs (Z79.84) and oral hypoglycemic drugs (Z79.84).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (expanded into subcodes).
